== Python mixer to control mic volumes ==

Angus has written a python mixer to control the mic volumes for the various headsets: "The speaker volumes will be added when I trace their path through the wolfson. It'll currently control handset, wired headset and bluetooth volumes. You currently need to tell it which to control as I have not found any dbus signals to tell what alsa state you are currently in. The displayed volumes may be wrong if you start the volume control before the alsa state change. One you use a control to set its volume it will reflect the state of the underlying hardware."

You'll need these 3 files

+

+

+

http://handheldshell.com/pymixer.py

+

http://handheldshell.com/volume.desktop

+

+

install pyalsaausdio and pygtk

+

+

copy pymxer /usr/bin

+

copy volume.desktop /usr/share/applications

+

+

You can now control mic volume.

Note that this program assumes it can write new alsa scenarios to /usr which needs root access or permissions that allow this. For example in debian these files are not modifiable by normal users.
